It sounds to me like this is going to be like the rules regression test
writ large; specifically the part that dumps out view definitions for
all the built-in views.  And that, quite frankly, has been a huge
maintenance burden and AFAIR has never once had any redeeming social
value in terms of catching a bug.  If you're testing things that way,
don't.  There might be some value in psql backslash command tests that
are designed to depend on just one or a few tables (or other appropriate
objects).  Dumping large fractions of the catalogs will just be a net
loss.
